Todo, even though he weighs a lot, thinks he is a lap dog. He loves to wrestle and is very spastic when it comes to seeing people when they come home. I've seen Todo grab his favorite ball and use that to control his excitement, just walking around with it till you give him attention. Todo loves to play fetch but is still struggling to bring it back to you. He will throw it right at your feet. Todo does not like sharing his toys, though, like tennis balls or benebones. Rex and Todo will share food out of the same bowl occasionally; if something is spilled onto the floor, Todo will become aggressive towards Rex and try to eat it, but thankfully he has now stopped doing that, but I still wouldn't trust him with some loose cheese. I still separate them because Todo has a bottomless belly and will eat out of the bowl until nothing is left. The only toy I've seen them both share is a tug-rope. Todo still really hasn't learned what tug of war is but will continue just grab the roap plop on the floor and let Rex pull him around. Todo will also, after a while, become agitated by Rex for continuously playing, but he has learned that he can go to his kennel and take a break. Other than that, Todo and Rex play very well with just themselves. Todo has had a few marking incidents inside since I first introduced him inside, but I haven't seen any since then. I haven't seen Todo make any attempts to get on the counters or in the trashcan. I haven't seen him do it in a while, but I guess out of jealousy he will try and get Rex from me, either the nice way by pushing him out of the way from the sofa or just by turning aggressive towards him, so I have to stand up to give both of them attention. Todo will eat his food without water but prefers it to be made like cereal. He is a social eater and won't eat just by himself, so you have to sit by him while eating. He has no problems with you moving up and around him while he's eating. He is a very sloppy but slow eater, and he will clean the floor of any loose pieces of kibble. He also does not like the feral cat here, whatever it is. The first couple of days of him seeing the cat, he would put his hackles up and growl and bark, but he has gotten used to the cat to the point where he is still interested but will not look like he's trying to eat the cat any longer. All together, despite a few incidents here and there, he has been very well-behaved and a great dog.
